Description
Technical field
The present invention relates to the technical field of performance parameter calibration, relate in particular to the performance parameter calibration that is applied to cell phone mainboard.
Background technology
The conventional method of cell phone mainboard performance parameter calibration generally is based on given acquiescence performance parameter value calibration, satisfies given condition up to the calibration result of performance parameter value and gets final product.The shortcoming of this calibration steps is: improper if the convergence method of performance parameter value calibration is sought, the time of calibration consumption is just long so; For example, the calibration of power of cell phone mainboard power amplifier, different capacity amplifier type, the time phase difference of calibration is very big, the reason that causes the alignment time to differ greatly is that the rule that increases of different capacity booster output is different, have to satisfy linear rule, also has to satisfy certain curve law.But it should be noted that: for given a collection of device, the result that its performance parameter value calibration passes through can fall in the smaller scope; Improve traditional calibration steps if can make full use of this characteristic, will certainly optimize traditional performance parameter value calibration steps and shorten the performance parameter value alignment time.
Summary of the invention
Deficiency at prior art, goal of the invention of the present invention provides the quickly calibrated method of a kind of cell phone mainboard performance parameter, be characterized in dynamically adjusting the bound that the performance parameter value dichotomy approaches according to calibrating successful mainboard, from this adjusted bound median, find out the desired value of performance parameter fast with dichotomy then; It is compared with existing conventional calibration method, has optimized the performance parameter calibration algorithm and has shortened the performance parameter alignment time.
Goal of the invention of the present invention is achieved by the following technical solution.
The quickly calibrated method of a kind of cell phone mainboard performance parameter of the present invention, described external power supply 101 powers up for tester 102, computer 103 and controllable electric power 105; Connect computer 103 and tester 102, controllable electric power 105 by the GPIB line; Connect tester 102 and cell phone mainboard 104 by the RF line; Connect controllable electric power and cell phone mainboard 104 by power line; Connect cell phone mainboard 104 and computer 103 by the USB Serial Port Line, this method may further comprise the steps:
(1), at first, move quickly calibrated program, automatically the test environment of configuration testing instrument and controllable electric power;
(2), secondly, quickly calibrated program is controlled cell phone mainboard automatically by the USB Serial Port Line and is entered test pattern, and by the automatic configurating mobile mainboard of USB Serial Port Line performance parameter test environment;
(3), last, quickly calibrated program reads mainboard performance parameter initial testing value from tester, and the automatic interim bound of in calibration process, dynamically adjusting performance parameter value, in a smaller scope, search the proper calibration value of cell phone mainboard performance parameter fast, method commonly used is two fens approximatiosses, also can select the approach method of other suitable performance parameter character for use.
For the ease of narration, the maximum magnitude that described supposition performance parameter X can allow is [A=MIN, B=MAX], if change the error ε of the error of tester output valve Y less than regulation with X, the value (being designated as X0) of X is exactly the desired value of performance parameter calibration so at this moment.The quickly calibrated method of this performance parameter may further comprise the steps: write down the 1st X value of calibrating successful mainboard correspondence and be X01, write down the 2nd X value of calibrating successful mainboard correspondence and be X02, judge the size of X01 and X02; If X01=X02 and X01 and X02 all more than or equal to A smaller or equal to B, remember A=X01-1 and B=X01+1 so; If X01<X02 remembers A=X01 and B=X02 so; If X01>X02 remembers A=X02 and B=X01 so; Constitute the later mainboard of making of interval [A, B] internal calibration new,, so just continue calibration back mainboard if in new [A, B], can find desired value; If the X calibration result is littler than A, just in that [NIN looks for desired value in A), if can find desired value X=X03, then remembers A=X03, if can not find desired value, then continues calibration back mainboard; If the X calibration result is bigger than B, just (B, MAX] in look for desired value, if can find desired value X=X03, then remember B=X03, if can not find desired value, then continue calibration back mainboard; Use the same method again, at the new later mainboard of interval [A, B] internal calibration that constitutes; If the siding-to-siding block length B-A that finds [A, B] greater than setting E, then begins to continue to use the same method the later mainboard of calibration from step; Till all mainboard calibrations finish.
Described quickly calibrated program is not manually to come the configuration testing environment by the test environment of GPIB line and the automatic configuration testing instrument of USB Serial Port Line, controllable electric power and cell phone mainboard.
Described quickly calibrated Automatic Program is dynamically adjusted the interim bound of performance parameter value in calibration process, in a smaller scope, search the calibration desired value fast, this quick calibration method is along with the increase of calibration mainboard sheet number, and it is more and more obvious that effect becomes.
